Celestron 93402 T‑Ring Adapter for Nikon cameras

This T-ring adapter from Celestron connects Nikon SLR and DSLR bodies to telescopes and spotting scopes, making astrophotography and digiscoping simpler by providing a secure bayonet mount and standard T-thread interface. It is useful for photographers who want to attach their Nikon 35mm-format cameras to optical instruments for planetary or terrestrial imaging.

Key Points

The adapter locks to the camera body like a lens, ensuring stable contact during long exposures and when using heavy optical accessories. It accepts standard T-threads, so it connects to a wide range of camera adapters, extension tubes and telescope accessories. Consider that it is designed specifically for Nikon bayonet mounts, so compatibility depends on the camera's mount type.

Technical Specifications

• Brand: Celestron
• Mount compatibility: Nikon SLR and DSLR bayonet (35mm format)

Practical Tips

Attach the adapter to the camera first, then to the telescope focuser or eyepiece adapter to reduce the risk of dropping sensitive equipment. When capturing stars or planets, use a sturdy tripod and mirror lock-up or electronic front-curtain shutter to minimise vibration, especially during long exposures. If you plan to use additional extension or focal reducers, check that the combined assembly still allows enough back focus for your camera to reach focus according to the telescope specifications.

Usage Recommendations

This accessory suits users transitioning into prime-focus photography with existing Nikon bodies, offering a straightforward mechanical interface for digiscoping projects. Note that some modern mirrorless or non-Nikon bodies may require an extra adapter to mount the T-ring, and focal length or field coverage will depend on the specific telescope or spotting scope in use.
